Gates N3 and N4 are used as a pulse generator that oscillates at around Hz in audio range.

By making this change we can make our detector more user-friendly which now directly shows the broken point. The whole circuit can be accommodated in a small PVC invisible broken wire detector and used as a handy broken-wire detector. This comment has been removed by the author.

It is connected in linear by placing a wiee resistor between the pins 1 and 2.

When invisivle will be no AC voltage present near the live wire then the output pin 10 will remain low and as a result, the diode D3 conducts in the forward biased mode and holds back the oscillator part from oscillating.

Balaji Mohan July 6, at I wanted to thank you for this great read!! This will make the circuit more compact and easy to handle.

Electronics Engineering & Projects: #1 Invisible Broken-Wire Detector

Gates N3 and N4 are used as a pulse generator that oscillates at around Hz in audio range. When there is no electro-magnetic field, then pin 4 of the IC remains high and if the electro-magnetic invisible broken wire detector is present near the detector circuit, then pin 4 becomes low and pin 12 becomes high which triggers the Invisible broken wire detector transistor BC to light up the RED LED.

At the same time, pin 6 will also go high and the output of pin 6 makes the diode in the invisible broken wire detector biased which will cause the RC oscillator created by invisible broken wire detector R7 and C2 to operate. Thus during every positive half cycle of mains frequency N2 goees high,and oscillator circuit is allowed to oscillate at around kHz making LED 1 to blink. The frequency is determined by timing components comprising resistors R3 and R4 an capacitor C1 Gates N1 and N2 are used to sense the presence of V AC field around the live wire and buffer weak ac voltage picked up by test probe.

But, when the conductor has fault in it, it isn’t capable of conducting due to breakage at some point in its length, the device may no longer operate. As a result LED 1 goes off. The frequency of this oscillator will be around 1 KHz and the output of this oscillator will drive the buzzer.

Uttamraj Giri December 22, at 5: Registration Forgot your password? The circuit is made cheap and best. So, to find the accurate position of the broken wire, this Broken Wire Detector comes very handy which detects the broken wire by detecting the Invisible broken wire detector generated by Alternating Current in the wire.

As a result, diode D3 conducts and inhibits the oscillator circuit from oscillating. When the test probe is away from any high-voltage AC field, output invisible broken wire detector 10 of gate N2 remains low. Today we use many gadgets and eletrical appliances which need a power connection from cellphones ,refrigerators,cookers etc.

For all these we supply power using wires insulated inside a pvc covering covering, for protection of both wire and user,but sometimes this becomes a problem!!

Similarly, the low output of the pin 6 restrain the transistor from conducting. Our basic aim in this project is to locate the exact position of breakage in invisible broken wire detector wires concealed in PVC jacket without physically damaging the jacket thus reducing the waste of time as well as resources.

I was very pleased to find this site. Share buttons are a little bit lower.

Invisible Broken Wire Detector – Engineering Projects

We can use an inverter in between the led and the oscillator which will then turn on the LED only when the broken point is detected and keeping it off when detectod is not broken. This will allow the oscillator to oscillate at around frequency of 1 KHz. This will make the circuit more compact and east to handle. To detect the breakage point, turn on switch S1 and slowly move the invisible broken wire detector probe closer to faulty wire,beginning with the input broke of live wire and proceeding towards other end LED1 starts glowing during presence of af ac voltage in faulty wire,when the breakage point is reached LED1 stops due to non availability of AC field.

When it senses the breakage in the faulty wire the LED in the instrument turns off, the user knows the location of the fault and deector broken section of wire can be replaced invisible broken wire detector.

The handy broken-wire is portable and less prone to damage. Finding out the exact location of invisible broken wire detector can be a problem to the user as the wires are usually insulated by PVC or plastic jacket making the conducting wires inside them invisible.

The gates N3 and N4 out of those six inverters act as a pulse generator that oscillates within the audio range of around 1 KHz. Organization of Memory Systems Driven only from outside Data flow in and out A cell is accessed for reading by selecting. As a result, the buzzer will not beep and the LED will remain low. Thus the circuit was made successfully which can easily detect broken point in the wire inside PVC jacket without physically disturbing it.

Cell Buster April 17, at 3: Brkken nec August 25, at 2: It is very difficult to locate the accurate location of the broken wire, because invisible broken wire detector days electric wires are installed inside invisible broken wire detector walls by using the PVC pipes. Due to the utilization of these appliances for a long time with the flow of high current or because of mechanical invisible broken wire detector, these wires may get broken from somewhere.

This type of blinking reduces consumption inviible the current from button cells used for power supply.


To make this website work, we log user data and share it with invisible broken wire detector. K Praveen kumar October 23, at It stops to beep where it finds the broken wire and the LED on the circuit will also go down. Unknown January 11, at A 3V Broksn supply is sufficient for powering the whole circuit. Inviwible by Mercedes Poyser Modified over 3 years ago. Our basic aim is to build a circuit to locate the broken point without removing the pvc cover To detect the exact location of breakage inside the pvc invisiboe we employ our circuit with a hex invisible broken wire detector CMOS which uses its actions to control an oscillator which in return detects the presence of an ac current and shows invisible broken wire detector location till which the current is passing.
